To all whom it may concern:

Be it known that I, WILLIAM S. BARKER, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvements in Refrigerators or Cold-Storage Apparatus; and Ldo asclare the following to be a full, clear, and exact description of the invention, such as' will enable-others skilled in'the art to which it appertains' to make and use the same, reference being had to the accompanying drawmgs, and to the letters and'figures of reference marked thereon, which form a part of this specification. f I i Tl'llS invention relates to improvements in refrigerators or cold storage apparatus.

The object of the invention is ,to-provide a cold storage apparatus in which articles of food may be kept and which does not re-' quire any of the usual means such asice or cold air for preserving a low temperature.-

In the accompanying drawings,Figure 1 is a vertical longitudinal section. Fig. 2 is ortion of the casing being broken away an the receptacle beingelevated. Fig. 3 is a top plan view with the head broken away to show the interior of the apparatus. Fig. 4 is a sectional of a refrigerator.

detail view of the upper portion ofthe apparatus. Fig. 5 is an enlarged view of a portion of the upperhorizontal frame member showing the means for securing the chain when the inner member is elevated.

The casing 1 is constructed preferably of galvanized iron and is of acyhndrical form and of suitable depth to serve the purposes This outer casing is embedded in the ground and the upper end thereof should be a'suita-ble distance above the surface of the earth, ap roximately as shown in Fig.1. Secured members 14 which are oined to an upper horiz'ontal member 15 which members constitute a frame above the ground. Withinthe casng 1 .is loosely placed a cylindrical receptacle 2 which may be freely moved in or out of said casing in a manner presently described. i i 1 The receptacle has an open side throughout its length, as shown in Fig. 2, and a series of shelves 3 which are supported on lugs 4 arranged on the interior ofsaid receptacle. These shelves may be placed a greater or less distance apart, as may be v o the'opposite.

sides of said casing are the vertica required. Upon these shelves the various articles are placed, such as the usual houseratntednbvfaa, 19 10.

hold articles commonly kept in refrigerators. As the "receptacle 2 is inclosed, the food upon the shelves 3 will not be contaminated by dust when the receptacleis above the ground; the opens ide of the receptacle 1 may be turned away fromthe' direction of the wind in there is any" air stirring;

and further, when l the receptacle -is=withm the casing the foodfis'protected'from any mold that may accumulate onthe innerside of thecasing. The upper ehdof'the casing l is provided with anf'annular gutter 5, {the upper-end of which lies below theupper end of said casing.fl This gutterorj trough like I member is providedwithwater whichforms a seal preventing .i11sectssfrom-enter ng the interior of the apparatus. Theupper end of the receptacle is provided with ahead consisting of twometallic parts 8' and'9 between-w 011' is placed a suitable non-heat conducting material, such for example as' mineral felt 7. The up er member 9 of said head extends outwar 1y beyond the circumference of the receptacle and has its extreme circumferential edge projected downwardly into the water seal 5, as'shown at 6 in Fig. 4. Such an extension of the edge of said cover into the water in the annular trough 5 prevents the possibility of insects entering the apparatus from the surface of the ground. The receptacle may be supported upon the upper end of the casing'or upon the bottom of said casing.

Owing to the fact that the water trough 5 terminates at a point below the upper extreme end of the casing, the water can never enter said casing from the trough. In the head of the receptacle, as just described,

there is a vent or opening 11 consisting of a tubular member which extends above the 'upper side 9 of said head. The upper end of this vent 11 is provided witha wire screen 16 which prevents any dirt entering the interior of the apparatus while at the same time it does not obstruct the free. circulation of. air. V Owing to the extension of the vent 11 above the upper member of the head rain is prevented from entering the interior of the receptacle from the upper side of the head. It will be noted that the head is of tapered form and that water fallmg thereon w1ll run down the side to the annular trough 5. The vent is "provided with a cap 12 which is rigidlysecured thereto and lies a suitable distance above vent; receptacle elevated whenever git is rdesired to remove articles -therefroiii jar: wiplaes articles thereandisaid-nlemberafiords means-for supportmg the chain while the receptacle is being 10- as-in' Figi112, the cha1nmay be secured to'a in,*by"means orgasm-16gis'atmhed to a loop 13 secured to fthefuii'per "side off the-meat; Ih sa a 1 n d v a upper hor zontal "me'mber15 Bfthe' frame elevatedg v-When the receptacle; is elevated,
